• A. Router
• B. Node
• C. Switch
• D. Bridge

Answer: (B)

In networking, a node is any device that has a network interface and can send or receive data on the network. A device with at least one network interface card fits this definition because the NIC provides the actual connection to the network and the ability to address and communicate. So, the broad term for such a device is a node.

The other terms refer to specific kinds of network devices with particular roles: a router connects different networks and routes packets between them, a switch forwards frames within a local network, and a bridge connects network segments at a similar layer. While those devices are indeed nodes, the question is asking for the general term, which is node.
